[[:file:applying-gravity-in-petroleum-exploration_fig15-1.png|Figure 1]] is a schematic of the earth, showing its gravity field (left) and magnetic field (right). The gravity field always points downward; thus, the measurements can be scalar. In contrast, the magnetic field can point in any direction; therefore, vector information is more important in interpreting magnetics.
